"Theobject of thisinvention is t'oi provide an improved" metallic seat for" the rail in order that the railway cross tie he pr0= te'cted I asfully asp'ossihle' from the inj urious effects dueto-the'working of the' rail onits' {(3- seat in"the-pas'sing of tr'aflic'over thera-ils whieh'oausesmmeor less Wear and tear on theiwoodti e; V

Theme of a metallic tie plate is quite common' anrl'generally'recognizedas necessary" 1"5 in'railroa'd practice-today. Itso'bjectbeing to; prolong; the life of the Wood tie. The

ideal condition for prolonging the life of thewood tie would. *e'ohsist in providing: such pi'btection'to the tie as'would effect a mini"- ao ninmwear' and tear. D eterioration'iofthe tie isLIaI-geLY {clue to theuse of spikes in fastening' the rails through the tie plate to: the tie.- Primarily the use" of. the spike. distorts the Wood fi'herfimthe tie" and as the trafiic clevelopsquite'often the; spike is loosened from the position 4 of its original fastening. with the resultthat its effectiveness as u a: means ofiholdingdown the railzis practical 1y destroyed;

Further advantagesof this invention are that will prevent the" slewing of the ties and Willact effectivelyas a' means'forfire venting creepinglof' the rails] The construe tion and design'are such thatthe plate may he eatherproofedand will hold itsoriginal shape for almaximum periodof time, and: the plate can be made of lighter material than other types of plates-heretofore'pro- Videdand therefore can' b'e manufactured in quantities at less cost than 'canordinary" g A preferred embodim nt ofmYifive'ntibh' is set forth in the following specifications and V accompanyin drawings byflway of 'illustration and not of limitation-.

Similar numerals refer tosimilar parts throughout thelseveral Vie-W's i In the drawing, 1'0" designates a, portion ofavwboden-tie of the kind 'commonly used in railroad construction. Mounted'upon the i tie, thereisshown a; tie plate 11. This tie-" plate llis adaptedQas illustrated, to "extend along the top of the tie at -tliep0int'w11ere the rail engages: therewith. The tie plate is illustrated as having an inwardly extend ing tongue or projection which projects centrally alon th tie and at'itfs innermost-end there isp'rovided a means 112 which"n;aybe* a bolt, alagf screw, or, ordinar jsgike for securing the tie i late positibifandhgainst' displacement upon the tie,

In the drawing a washer 13 is shown as co-operating with the bolt 12 in order that the plate may be drawn tightly against the tie. At the point where the rail engages the tie plate 11 there is provided a pair of distance or limit plates 14: which are secured thereto on each side of the rail flanges and act as guides for the rail setting and to maintain a constant gauge of the rails as will hereinafter appear.

Specially designed rivets 15 are shown as being secured to the tie plate 11 and extending through holes in the limitcor distance plates 14. The heads of these rivets are provided with flat sides so that the rivets may with the use of a suitable'wrench be turned through 180 in either direction. The heads of the rivets are eccentrically positioned in relation to their body portion so that turning the head will cause it to assume different positions in relation to the distance plates 14: and rails 17. The rivets shown at 15 are in their normal position for locking the rails 17 against the tie plate 11 and the rivets shown at 16 have been turned through 180 to a position so that the rail 17 may be conveniently raised from its. seat without disturbing the position of the tie plate attached to the wood tie. The lower rounded. ends of the rivets extend below the lower surface of the tie plate where they bear upon the tie and serve as calks to prevent slippage of the plate uponthe tie. The tie plate 11 has its side edges bent downwardly to an angle of 90 forming flanges 18 designed to fit over the sides of the tie, these flanges serving to prevent the tie from slewing beneath the rails and in addition reinforce the tie plate immediately under the rail and act in combination with the rivets 15 to prevent the rails from creeping.

While certain features of the present invention are more or less specifically described, it should be understood that various changes of the design may be resorted to without departing from the spirit and scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A tie plate of thecharacter described comprising a main plate portion adapted to support a rail, an inwardly extending portion formed integral with said main portion adapted to be secured to the tie at a point between the rails, and limit plates upon said main portion adapted to co-operate with the railholding means to prevent movement of'said rail longitudinally of the tie.

2. A tie plate comprising a main plate portion having its edges bent downwardly to conform to the top of a railway tie, limit plates to engage a railway rail, a holding boltto secure said tie plate tosaid tie, and

rivets for holding said rail in close engagement with the tie plate, said rivets being journalled in the tie plate and having heads eccentrically disposed so that turning of the rivets causes their engagement and disengagement with the rail as desired.

3. A tie plate of the character described comprising means for securing the tie plate to a tie whereby vertical movement of a rail supported by said tieplate will not cause damage or deterioration of said tie, means carried by said tie plate for preventing longitudinal movement of said rail in relation to said tie, and means having eccentrically disposed heads for securing said rail to said tie plate.

4. In a rail mounting the combination of a tie plate having a body portion with its edges bent downwardly to engage the sides of a tie, a single holding bolt adapted to pass through a hole in one end of said body portion and secure said tie plate to said tie limit plates secured to the upper surface of said body portion adapted to engage the outer edges of the flange of a rail, and means consisting of specially designed rivets extending through holes in said tie plate and said limit plates for securing said rail in close engagement to said tie plate.

5. In a rail mounting the combination of a tie plate having a main body portion adapted to engage the top and upper edges of a railway tie, a holding adapted to pass through a hole in one end of said body portion and securethe same to said tie, limit plates fastened to the upper surface of said tie plate and engage the outer edges of theflange of a rail, and means for detachably securing said rail to said tie plate, said means consisting of rivets extending through holes in the tie plate and limit plates having eccentrically disposed heads on their upper ends so that turning of-said rivets will cause their engagement and disengagement with therail as desired.

6. The combination with a rail and a tie forming a support therefor, of a tie plate interposed between the tie and the rail, means securing the tie plate to the tie, a plurality of rotatable bolts carried by the tie plate and disposed on opposite sides of the foot flange of the rail, and eccentric heads on said bolts movable into and out of engagement with the foot flange of the rail.

7. The combination with a rail and a tie forming a support therefor, of a tie plate interposed between the tie and the rail, a pair of limit platesmounted on the tie plate, one on each side of the foot flange of the rail and 'engageable therewith, a pair of bolts extending through the tie plate and the limit plates and securing the limit plates against removalfrom the tie plate, said bolts being free to rotate with relation to the tie plate and the limit plates, an eccentric head on each bolt movable into and out of engagement with the foot flange of the rail, and means whereby the tie plate is securedto the tie.

8. The combination with a rail and a tie forming a support therefor, of a tie plate interposed between the tie and the rail, a pair of limit plates mounted on the tie plate,

one on each side of the foot flange of the rail and engageable therewith, means 00- operating with the limit plates to secure the rail against removal from between the limit plates, and other means to secure the tie plate to the tie.
